Answer 1

Answer:

x≤−9 or x≥5 or x=0

Step-by-step explanation:

Let's solve your inequality step-by-step.

x2(x+9)(x−5)≥0

x4+4x3−45x2≥0

Let's find the critical points of the inequality.

x4+4x3−45x2=0

x2(x−5)(x+9)=0(Factor left side of equation)

x2=0 or x−5=0 or x+9=0(Set factors equal to 0)

x=0 or x=5 or x=−9

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x≤−9(Works in original inequality)

−9≤x≤0(Doesn't work in original inequality)

0≤x≤5(Doesn't work in original inequality)

x≥5(Works in original inequality)

Answer:

x≤−9 or x≥5 or x=0

Solve for x. x=16*4 to the second power +34*m. When m=5​

Answers

If what I said in the comments was right then first we have to substitute m.

x = 16(4)^2 + 34(5)

16(4) = 64

64^2 = 4096

x = 4096 + 34(5)

34(5) = 170

x = 4096 + 170

x = 4,266

Challenger Elementary School has 800 students. Every Wednesday, 12% of the students stay after school for Chess Club. How many students attend on Wednesday’s?

Answers

Answer:

96 students attend chess club after school on Wednesday's.

Step-by-step explanation:

To solve this problem, simply multiply 800 x 0.12.

    800 x 0.12 = 96

I hope this was helpful to you! If it was, please consider rating, pressing thanks, and marking my answer Brainliest. It would help a lot. Have a great day!

Answer:

[tex]\huge\boxed{\text{96 students}}[/tex]

Step-by-step explanation:

In order to find how many students stay back for Chess Club, we want to find 12% of 800.

To do this, we can set up a percentage proportion.

[tex]\frac{12}{100} = \frac{x}{800}[/tex]

We can now solve for x by cross multiplying.

[tex]800 \cdot 12 = 9600\\9600 \div 100 = 96[/tex]

So, 96 students attend Chess Club on Wednesdays.

Hope this helped!

Step-by-step explanation:

Both B and C

B)

2/5 = 0.4 (which terminate as decimals)

Similarly

C)

-1/4 = -0.25 (also terminates)

But A and D do not terminate

As for A) 1/3= 0.33333333..........

and for D) 7/9= 0.777777777......

In both cases the decimals are a never ending sequence or in other words does not terminate at all. They are irrational numbers.

A 1/2 cup serving of ice cream contains 140 calories. How many calories would be in a 3/4 cup serving?

Answers

Answer:

There would be 210 calories in a 3/4 cup serving.

Step-by-step explanation:

1/2 of 140 = 70

70 = 1/4

70 x 3 = 210 = 3/4

I hope this helped you! If it did, please consider pressing thanks, rating my answer, and marking as Brainliest. It would be a big help! Have a great day! :)

Based on the number of calories in 1/2 cups, the number of calories in 3/4 cups is 210 calories.

Number of calories in 3/4 cup

You can use direct proportion to solve for this by assuming that the calories in 3/4 cups is x:

1 / 2          :         140 calories

3 / 4          :        x

Cross multiplying would give:

1/2x = 105

x = 105 ÷ 1/2

x = 210 calories

In conclusion, there would be 210 calories in 3/4 cups.

Answer:

Step-by-step explanation:

the bat is 12. the pumpkin is 5. and the weird looking thing is 14

14 plus 14 plus 12 is 40

12 minus 5 is 7

5 plus 14 is 19

14 minus 5 plus 12 is 21

Answer:

  21

Step-by-step explanation:

Green bat:   x

Purple bat:   y

  Pumpkin:   z

Given:

  2x + y = 40

  y - z = 7                ===>      y = 7 + z

  z + x = 19             ===>       z = 19 - x

Substitution to find green bat x:

  2x + y = 40

  2x + (7 + z) = 40

  2x + 7 + z = 40

  2x + 7 + (19 - x) = 40

  2x + 7 + 19 - x = 40

  x + 26 = 40

  green bat:  x = 14

Substitution to find pumpkin z:

  z + x = 19

  z + (14) = 19

  z + 14 = 19

  pumpkin:  z = 5

Substitution to find purple bat y:

  y - z = 7

  y - (5) = 7

  y - 5 = 7

  purple bat:  y = 12

Solve for x - z + y:

  14 - 5 + 12 = 21
